Full Answer

Gravel out of water weighs almost half as much as dry gravel. This measurement is for construction-grade gravel, used for building and landscaping purposes. The average particle size for this type of gravel is about 1/4 of an inch. For lighter-grade, smaller-particle sand, the weight is lower. However, gravel with sand added to the aggregate has dramatically increased weight. Dry gravel has a specific gravity, or the ratio of density compared to that of water, of 1.52.
